Virgin Mobile Internet on Blackberry Curve 8530?

I have the bb curve for virgin mobile and yes if you go somewhere that has a wi-fi connection you can connect to it for free. and it would be even faster. And no VM does not limit the sites you can go on, I can go on any site I wish. Its a HTML browser which means you can access any site that you could access on a computer. And for your last question, You dont pay for 3g anyway. the blackberry for VM is 3g even before you buy it , because sprint bought virgin mobile and virgin mobile runs on sprints network. And sprint is 3g . So if you use wi-fi your internet would be super fast. I dont really use wi-fi because I'm never in a spot that has wi-fi and my internet on my phone is super fast.
